Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic flowmeters, in particular to an electromagnetic flowmeter with a dustproof structure. Background Art

[0002] An electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of a conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field.

[0003] In order to facilitate the installation of the electromagnetic flowmeter, the installation pipe of the electromagnetic flowmeter is usually in an open state. During the installation process, the flanges on both sides of the installation pipe will be accurately docked with the corresponding flanges on the pipe to be installed, thereby realizing the stable installation of the electromagnetic flowmeter on the target monitoring pipe. Before installing the electromagnetic flowmeter, if its installation pipe is directly exposed to the external environment for a long time, it may be invaded by debris or dust due to the lack of dust-proof devices. Therefore, in order to ensure the installation quality and the purity of the subsequent substances in the pipeline, the inside of the installation pipe must be thoroughly cleaned in advance. If this step is ignored, the substances in the pipeline may be contaminated. Therefore, it is necessary to develop an electromagnetic flowmeter with a dust-proof structure. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0026] See also Figure 1-Figure 4 , shows a schematic diagram of the structure of an electromagnetic flowmeter with a dustproof structure according to the present invention, please refer to Figure 1-Figure 4 , a detailed introduction is given to an electromagnetic flowmeter with a dust-proof structure.

[0027] An electromagnetic flowmeter with a dustproof structure includes an electromagnetic flowmeter body 100, wherein the electromagnetic flowmeter body 100 includes a mounting pipe 110 and flanges 120 provided at both ends of the mounting pipe 110 for connecting to pipelines;

[0028] The dust baffle 200 is symmetrically rotated and arranged on the outer side of the flange 120. The surface of the dust baffle 200 close to the flange 120 is provided with a sealing rubber layer, and the sealing rubber layer is in contact with the surface of the flange 120. The flange 120 is in the shape of a semicircular plate. A sealing rubber strip 210 is provided on the side where the two dust baffles 200 are close to each other. When the two dust baffles 200 are closed, the mounting tube 110 is in a closed state. The provided sealing rubber layer and sealing rubber strip 210 facilitate sealing the mounting tube 110 when the dust baffle 200 is closed.

[0029] The locking mechanism 300 is arranged below the two dustproof baffles 200 and is used to lock the position of the two dustproof baffles 200 when the two dustproof baffles 200 are closed. The locking mechanism 300 includes a mounting block 310 fixed below one dustproof baffle 200, and a socket 320 is opened on the side wall of the mounting block 310. A mounting bracket 330 is fixedly set below the other dustproof baffle 200, and a mounting groove 340 is opened on the side wall of the mounting bracket 330. The inner cavity of the mounting groove 340 is slidably penetrated by an insertion rod 350 for fitting into the socket 320.

[0030] Furthermore, a fixing block 220 is fixedly provided on the upper edge of the flange 120 , and a connecting block 230 is fixedly provided on the top of each dust baffle 200 near the fixing block 220 , and the connecting block 230 is rotatably connected to the fixing block 220 via a rotating shaft 240 .

[0031] Furthermore, a pinch plate 250 is provided on one side of the dust shield 200 away from the flange 120. The outer side of the pinch plate 250 is provided with anti-slip grooves. When the user needs to close the two dust shields 200, the thumb and index finger of one hand can pinch the two dust shields 200 to ensure that the two sealing rubber strips 210 are tightly attached to each other, making it convenient to lock the two dust shields 200 through the locking mechanism 300.

[0032] Furthermore, one end of the insertion rod 350 slides through the side wall of the mounting groove 340 and is used to be inserted into the hole of the insertion hole 320. The outer diameter of the insertion rod 350 is equal to the inner diameter of the insertion hole 320.

[0033] When and only when the two dust shields 200 are closed and the sealing rubber strips 210 are in close contact with each other, the insertion rod 350 and the insertion hole 320 are aligned, that is, when the insertion rod 350 is inserted into the insertion hole 320, the outer wall of the insertion rod 350 and the inner wall of the insertion hole 320 are in close contact with each other. If the rod 350 does not move laterally along the hole 320, it cannot be withdrawn from the hole 320, so the two dust shields 200 cannot be opened;

[0034] The cam 360 is engaged with the cam 361 and is clamped in place so that the cam 361 is held in place until the cam 361 is engaged.

[0035] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
